Building Energy Codes Programs

NOTICE (03/01/2019): Arkansas is currently reviewing the latest editions of model codes and plans to update the statewide Energy Codes. The adoption date is not yet clear. Send your comments or inquiries to energyinfo@adeq.state.ar.us, or subscribe to the Energy Efficiency Arkansas email list for key announcements.

Arkansas currently uses the 2014 Arkansas Energy Code for commercial and residential construction, which is based on the International Energy Conservation Code-2009 and ASHRAE 90.1-2007. The Arkansas General Assembly authorized the Arkansas Energy Office to promulgate these regulations in Section 3(B)(2)(c) of Act 1981.

Residential Energy Resources

Home energy codes not only save money on an occupant’s utility bills, but also provide a safer, healthier, more comfortable indoor environment. Have you experienced excessive indoor humidity in the summertime? Mold problems or wood rot? Stale air and allergies? Uncomfortable temperature zones in parts of the house? Carbon Monoxide alarms sounding? Excessive radon levels?

Proper compliance with the Arkansas Energy Code, like all building codes, helps standardize quality construction and prevent health and safety issues.

The free REScheck product group makes it fast and easy for builders, designers, and contractors to determine whether new homes, additions, and alterations meet the requirements of the IECC or a number of state energy codes, including Arkansas. REScheck also simplifies compliance determinations for building officials, plan checkers, and inspectors by allowing them to quickly determine if a low-rise residence meets the code.

REScheck is appropriate for insulation and window trade-off calculations in residential detached one- and two-family buildings and multi-family buildings three stories or less in height above grade, such as apartments, condominiums, and townhouses. REScheck works by performing a simple U-factor x Area (UA) calculation for each building assembly to determine the overall UA of a building. The UA that would result from a building conforming to the code requirements is compared against the UA for your building. If the total heat loss (represented as a UA) through the envelope of your building does not exceed the total heat loss from the same building conforming to the code, the software generates a report that declares your building is compliant with the code.

REScheck Desktop can be downloaded and installed directly to your desktop, while REScheck-Web™ is accessible directly from the website without having to download and install.

The Arkansas Energy Code is a combination of the International Energy Conservation Code and Arkansas Supplements and Amendments. Enforcement in jurisdictions that have adopted the code is done by the local government through the municipality’s established inspection process.

Commercial Energy Resources

COMcheck is free and is one of many software tools available to determine compliance with the Arkansas adopted standards IECC-2009 or ASHRAE 90.1-2007.

Retail and service buildings use the most total energy of all the commercial building types. This isn’t too surprising when you think of all the stores and service businesses in most towns. Offices use a large share of energy, too. Education buildings, like Arkansas schools, use 13 percent of all total energy, which is even more than all hospitals and other medical buildings combined! Lodging buildings (like hotels or dormitories) use 8 percent of all energy. Warehouses and food service (like restaurants) each use 7 percent. Public assembly buildings, which can be anything from libraries to sports arenas, use 6 percent; food sales buildings (like grocery stores and convenience stores) use 4 percent. All other types of buildings, like places of worship, fire stations, police stations, and laboratories, account for the remaining 10 percent of commercial building energy.
